中文摘要: 在2003年6月下旬至7月上旬梅雨期,淮河流域出现了持续强暴雨。7月4日08时～5日08时,安徽省部分地区出现特大暴雨,其中滁州273.7mm；滁州4日20时～5日20时日雨量为351.7mm。使用MUSCAT技术对这次特大暴雨进行了双多普勒雷达三维风场反演,研究表明,中低层辐合线和中尺度气旋是造成此次暴雨的重要原因;辐合线造成低层水汽的大量集中也为其提供了有利的环境条件。

Abstract:The heavy rainfall existed for a long time in the Jianghuai area in 2003 Meiyu period resulted in a flood. A heavy rain occurred in the Dual-Doppler coverage, up to 351.7mm rainfall in 24h from 20:00 on July 4 to 20:00 on July 5 in Chuzhou, Anhui Province. The three-dimensional wind of the heavy rain were retrieved by MUSCAT (multiple-Doppler synthesis and continuity adjustment technique) using the dual-Doppler radar volume scan data. It showed that the convergence line and the meso-cyclone at the low level play an important role in this heavy rain event. The vertical circulation is also clear in the event.
